Abstract

In this study, we prepared series of recycled polyethylene terephthalate (RPET)/polyethylene (PE) blends using melt extrusion. The effect of RPET content on crystallization behavior and thermal conductive properties of the resultant blends were investigated using differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA), etc. RPET was found to exert nucleating effect on the melt crystallization of PE. The Agari model presented fairly reasonable prediction of thermal conductivity as a function of RPET loading. The melt cooling process was predicted with an enthalpy transformation method (ETM), which is a well-established mean of evaluating the instantaneous heat conduction of crystalline polymers/composites, and the obtained curves were consistent with our experimental results. Besides, a four-parameter model (FPM) was adopted coupled with an in-situ temperature measurement in order to further disclose the solidification and crystallization kinetics of PE in the presence of RPET in the blends.
